To @ZZ whom it may concern.'

Be it known that we, JoNAH L. HARTsnLL and WILLIAM J. WEST, citizens of the United States, residing at Concord, in the county of Cabarrus and State of North Carolina, have invented new and useful Improvements in Card-Feeler Stop-Motions, of which the following is a specification.

This invention relates to stop motions for looms, and has particular reference to a card feeler stop motion for jacquard heads.

It is an object of the present invention to provide a stop motion of this character which will operate upon the first pick of the jacquard mechanism, so that practically no damage will result from the breaking of the lacing or cards, or the displacement of the latter on the card cylinder. Various devices have heretofore been invented and have been employed for stopping the loom upon the displacement of the cards on the cylinder. These devices, however, have not been eEective until the mechanism has proceeded in operation to a considerable extent, frequently resulting in the bending or breaking of the jacquard needles, the destruction of the cards, and the loss of a considerable production of cloth.

. jacquard head applied toa loom of common construction, the parts being shown somewhat diagrammatically.

Fig. 2 is a detail, enlarged, perspective view of the card feeler stop motion mechanism of this invention.

Fig. 3 is a detail perspective view of one end of the jacquard head showing the improvement applied thereto and illustrating the position of a displaced card about to attuate the improved.- ,St-Op @tiva Fig. 4l is a detail enlarged side elevation of one end of the jacquard head having the improvement applied thereto.

Fig. 5 is a detail enlarged top plan view of the card feeler of this invention.

Referring to the drawings, and first to Fig. 1 wherein is diagrammatically shown a jacquard mechanism applied to a loom, the numeral 10 designates the usual gang-tree which supports the jacquard mechanism. The gang-tree 10 carries the usual jacquard frame or head 11 within which are mounted the griff frames 12 carrying the usual knives or griff bars 13. At the opposite ends of the frame or head 11 are disposed the card cylinders 14 arranged and operating in the usual manner. The cards 15 are shown as laced and passing over the cylinders 14.

The frame 11 is provided at its opposite ends with card feelers in the form of transverse bars 16 having pluralities of outwardly extending and spaced-apart ngers 17, the fingers 17 being adapted to rest of their own weight upon the top of the card cylinders 14. rlhe bars or rods 16 are hingedly mounted in any suitable manner upon the frame 11, such as by straps 18, whereby the card feelers may have a free and easy swinging movement. At one end of the bar or rod 16 is disposed an arm 19 which is of suitable curvature to pass over the top of the frame 11 and has upon its inner end a loop 2() encircling the upper end of a jacquard hook 21, the latter being mounted in the frame 11 in the manner of the usual jacquard hooks and being supplemental thereto. For each of the card feelers there is provided the above described mechanism, so that the improved mechanism is operable with respect to the cards and card cylinders at each end of the jacquard head.

The lower ends of the jacquard hooks 21 are provided with connecting wires 22 which pass down from the jacquard head to the loom proper and through an eye or guide 23 fixed preferably upon the end of the comber board 24 adjacent the shipper lever 25. From the eye or guide 23 the wires 22 pass down against the side of the loom and have connection with one arm of a bell crank lever 26 suitably pivoted upon the frame of the loom and having its opposite arm connected by vwire `27 with the shipper lever It is thus seen that the card feeler stop motion at each end of the jacquard head operates upon the shipper lever 25 so as to stop the motion of the loom should either one of the sets of cards become displaced on the card cylinders.

Normally, upon the advancement of the cylinder 14 the mechanism assumes the position shown in full lines in Fig. 4. In the tumbling of the cylinder to present a new card to the needles, as shown in dotted lines at 14a in Fig. 4L, the fingers are raised slightly without actuating the jacquard hook 21, as at 17a, and are permitted to drop by gravity into their normal position, as shown in the full lines1 as soon as the cylinder is in position to be advanced toward the needles.

Should the cards not seat properly upon the face of the cylinder, it is apparent that the cards would be raised and be held in such position by the card pins on the cylinder, and would consequently raise the fingers 17 and operate the stop motion as the cylinder 14 moves inwardly toward the needles. l/Vith the use of this mechanism it is apparent that the lingers 17 may be raised upon any displacement or inaccurate registering of the cards upon the cylinder, one instance being here illustra-ted and wherein the card lacing is shown as broken and a card 15b is permitted to swing out of alinement with the cylinder, as shown in Fig. 3. In this instance the card 15b falls upon the turning of the cylinder into engagement with the card pin and projects at one edge above the cylinder to engage the fingers and hold the same raised, as shown at 17b in Fig. Ll. The inward movement of the cylinder, as shown at 14", thus tends to further raise the fingers and insure the movement of and the registration of the jacquard hook 21 with the griff bar 1B. When the fingers 17 are turned up, the arm 19 is swung down and draws outwardly the jacquard hook 21 into the path of the vknife or griif bar 13, so that upon the rising of the griff frame the jacquard hook 21 is raised. The lifting of the jacquard hook 21 draws the wire 22 connected therewith and through the bell crank lever 26 throws the shipper lever 25 into position to stop the loom. llt will thus be noted that the loom is brought to a stop and the disordered card is detected before any damage can be done or before the cards are wound up upon the card cylinder. The cards may now be easily readjusted and relaced without great loss of time and also without `the necessity of repairing any parts of the mechanism.

It will be noted that this improved mechanism is so located upon the jacquard head that any irregularities in the cards are detected before the cards are permitted to pass into operative position, and consequently, "before any damage may result therefrom.

It is, of course, understood that various changes and modifications may be made in the above described structure, without departing from the Vspirit of the invention, and within the scope of the following claims.

Vhat is claimed is 1. ln combination with a loom, and a j acquard head controlling the loom and having the usual card cylinder and griff bars, of a card feeler` mounted upon the jacquard head and normally resting upon the top of the card cylinder, a jacquard hook having connection with said card feeler and adapted to be drawn into alinement withv one of said grifil bars on the lifting of the card feeler', and a connection between said jacquard hook and the shipper lever of said loom, to release the shipper lever upon .the vengagement of the jacquard hook with the griff bar.

2. A. card feeler stop motion for looms comprising a pivoted bar, a plurality of fingers outstanding from the bar adapted to rest upon the :top of a card cylinder, an inwardly extending arm carried upon the bar, a jacquard hook connected to the inner end of the arm and adapted to be drawn laterally upon the lifting of said fingers, and a shipper lever connection having attachment to said jacquard hook and adapted to be actuated upon movement of the acquard hook by -said fingers.

3. 1n a card feeler stop motion for looms, a pivoted card feeler normally resting against a card cylinder, and adapted to be tilted upon the misplacement of a card on the cylinder, a jacquard hookhaving connection with said card feeler to be actuated by the 4tilting thereof, and V-means connecting said jacquard hook to the shipper 'lever of a loom.
